Introduction
• Next Wave After Y2K– Web Development– E-Commerce– Linkage to Existing Systems– Web, Java and Cobol
• Project to teach Web/Existing System Integration using Net Express
Project Components• Web Component
– Forms and CGI Development– Java Script
• Data Base Component– Database Interface to Oracle– OO Cobol– Oracle Database Running on an NT
Server• Building, Packaging and Testing

Building and Testing• Building the Executable• Testing using Solo
– Animating• CGI Animation• DBI Animation - SQL Calls
– Testing the Java Script• Migration to the Web Server
– Oracle Client– Micro Focus OO Support
